求大佬救救迷茫的我

Because of: "每个方法都应返回调用它的方法的名称" Thread.currentThread().getStackTrace() is an array. The element of this array with index 0 represents the getStackTrace() method itself. An element of this array with index 1 represents the method we are currently in. I would name this the current method. This is the method that called getStackTrace(). The index 2 element of this array is the method that called the current method. (And this is what the task asks us.) You can try it all yourself: just print the method name of the element 0, the 1, the 2, etc.
